A compact, powerful 4G LTE Cat.1 platform based on the **Quectel EC200U series** — supports global LTE-FDD, dual SIM (nano + eSIM), Wi-Fi/BT scan, and integrated GNSS. Which LTE bands are supported? EC200U-CN: Optimized for China and Asia-Pacific EC200U-EU: Europe, Middle East, Africa, Australia, etc. Full band list in the datasheet — supports **LTE Cat.1 bis** up to 10 Mbps DL / 5 Mbps UL. Can I use both nano-SIM and eSIM at the same time? Yes — the board has **one nano-SIM (4FF)** slot and **one soldered MFF2 eSIM**. You can switch between them via AT command (AT+CUSIM). How do I communicate with the module? Connect via **USB-C** → appears as multiple COM ports: • Highest-numbered port = **Main AT UART** (115200 bps default) • Lower port = **Debug/Log port** Also exposed on pins: Main TX/RX and separate Debug TX/RX. Does it support GNSS (GPS)? Yes — integrated multi-constellation GNSS (GPS, GLONASS, BeiDou, Galileo). Dedicated **GNSS U.FL connector** for active antenna is provided. Is Wi-Fi / Bluetooth available? EC200U supports **Wi-Fi scan** and **Bluetooth scan** (passive only). Full BT/Wi-Fi transceiver is not included, but a shared **U.FL connector** is present for external antenna if you use a variant with radio. How to power the board? Two options: • **USB-C** (5 V) → onboard 2 A regulator • External **5 V** on the +5 pins (peak current ~1.8 A during TX bursts) What do the four LEDs mean? • **D1**: Module operating status • **D2**: Network registration • **D3**: Network activity / data • **D4**: Power ON Can I upgrade firmware or enter DFU mode? Yes — pull **USB_BOOT pin** high (connect to 3.3 V) before powering on → module enters USB download mode (Quectel QFlash tool). What are the board dimensions? Very compact: **42.72 × 39.60 mm** — perfect for breadboarding or integration into final products.
